Sistema sem fios para controlo de iluminação decorativa

Este projecto surgiu no contexto da solicitação de um dos clientes da empresa Castros Iluminações que pretendia um sistema de iluminação decorativa (baseada em LED) de dois conjuntos de 288 janelas, pertencendo cada conjunto a uma fachada diferente do edifício. Este sistema teria que prever a possibilidade de controlar a cor de cada janela individualmente, dando ao cliente a possibilidade de alterar o ambiente decorativo das fachadas do edifício. A utilização de comunicação sem fios foi justificada pela necessidade de evitar a quantidade enorme de cabos que seria necessário passar utilizando os sistemas comerciais convencionais e a impossibilidade de os esconder. Esta solução foi pensada para ser implementada num edifício com 14 Andares, facto que por si só inviabiliza a passajem de cabos. Para interligar todos os dispositivos de iluminação decorativa com um controlador portátil, e eliminar os problemas ligados à cablagem, foi utilizado o protocolo de comunicações sem fios ZigBee™. A escolha recaiu neste protocolo devido a factores como os seus baixos consumos, simplicidade do protocolo comparativamente com outras redes e o seu baixo custo. No desenvolvimento deste projecto foi utilizada a stack da Microchip©, versão gratuita, disponibilizada na internet e os seus transceivers de comunicação Zigbee™, MRF24j40MA. Para fazer a interface de comunicação com o utilizador, foi desenvolvida uma aplicação de Software para correr em computadores com ambiente Windows™. Esta aplicação foi desenvolvida em Visual Studio™ utilizando a linguagem C#. Foram efectuados alguns testes para se perceber a eficiência e robustez da comunicação ZigBee™ e apesar do número de dispositivos disponíveis para ensaios ser muito reduzido, foi possível verificar que, mesmo funcionando correctamente, o desempenho do sistema poderá ser melhorado, quer seja a nível da gestão das comunicações, quer a nível do software informático para controlo do ambiente decorativo das fachadas do edifício. O sistema, no actual estado de desenvolvimento, permite controlar a cor dos vários dispositivos da rede através do computador, com uma resolução de 24bits. A aplicação desenvolvida em Visual Studio™ permite controlar de forma simples e intuitiva para o utilizador, a cor do material iluminativo dos vários dispositivos da rede.

A realização plástica da heráldica do exército português

É feita uma síntese do trabalho de iluminura de escudos-de-armas destinados ao Exército Português pelos diversos artistas plásticos que integraram o Gabinete de Heráldica do Exército, sendo destacado o importante heraldista José Colaço sendo as iluminuras produzidas alvo de análise relativa à sua qualidade estética.

Influence of experimental illumination and seasonal variation on crossbreending mating in the snail Biomphalaria Glabrata

The crossbreeding activities of the Schistosoma mansoni vector snail Biomphalaria glabrata were counted in a laboratory aquarium throughout the year under two regimes of 12h light: 12h dark from 7 A., M. to 10 P. M. Mating increased significantly in Authmn and Winter and just missed a significant inverse correlation with temperature and a direct one with locomotion. Other similar experiments were carried out to compare mating under various ilumination conditions in complete daily cycle measurements. Mating counts decreased under the regimes which submited snail to a total exposure of 12h light and 12 dark during a daily cycle in the following sequence: 12h light: 12h dark alternating hourly with light gradient, 12h light: 12h dark, 1h light: 1h dark and 12h dark: 12h light. Under two constant illuminations, the mating scored less than under the previous conditions, except under 12h light. Under darkeness the mating count was lower than light conditions. There was no way to differentiate the night and day rhythms of mating on different days in each regime, except for mating under 12h light: 12 dark alternating with light gradient, constant dark and 12h dark: 12h light conditions. Mating increased in certain light and temperature conditions, in wich the intensities, should have an optimum value.

Risk Evaluation for Spoofing against a Sensor Supplied with Liveness Detection

The aim of this paper is to evaluate the risks associated with the use of fake fingerprints on a livescan supplied with a method of liveness detection. The method is based on optical properties of the skin. The sensor uses several polarizations and illuminations to capture the information of the different layers of the human skin. These experiments also allow for the determination under which conditions the system is deceived and if there is an influence respectively of the nature of the fake, the mould used for the production or the individuals involved in the attack. These experiments showed that current multispectral sensors can be deceived by the use of fake fingerprints created with or without the cooperation of the subject. Fakes created from direct casts perform better than those produced by fakes created from indirect casts. The results showed that the success of the attack is influenced by two main factors. The first is the quality of the fakes, and by extension the quality of the original fingerprint. The second is the combination of the general patterns involved in the attacks since an appropriate combination can strongly increase the rates of successful attacks.
